Thank you guys for the answers
is it possible to get the 6262 or the 6765 in a T4 divided housing?
and how the t4 housing will preform in meanning of hp until 9500rpm for both turbos?
Thanks again

Honestly, some of the difference probably is timing. Both cars are on AEMs, one is a 9:1 motor on Q16 the other is an 11:1 E98 motor. Both are running the same boost to make this power. I would think the sacrifice of 20 ft lbs to make 5 more whp and save a couple hundred dollars is a good trade...but what do I know

Lookin for a 6765 with divided t4 exhaust housing i've found this, but no feedbacks about how it works.....

We can build the 6262 in divded T4 .58, .70 and .84 A/R, and the 6765 (or 6265) in a whole host of different sizes.
In regards to the T04Z vs the 6262, the 6262 is going to come online a bit quicker all else equal. It uses a 71mm turbine as opposed to the larger P-Trim sized T04Z wheel (I believe it uses a 75mm turbine if memory serves).
I wouldn't consider the 6262 a larger power unit across the board, however it does compare amazingly well for the size of the compressor wheel. Another thing that needs to be taken into account is where the turbo will be operated. In an E98 case for example, especially with big cams and a small turbine housing as many people select, you will start to run into the flow restriction of the smaller turbine wheel which will lead to a precipitous VE fall off where high rpm torque and power will suffer.
In this scenario, at least the larger turbine housing would be recommended - but possibly also a move to the 6265 as we recommend for many Supra customers. It will be a bit slower to come up but it keeps the exhaust pressure more in check when you're using all of the compressor wheel, but again all applications are different of course and decisions like this are made simple with the addition of an exhaust pressure sensor so you really know what your pressure ratio looks like.

The 6262 makes good power for the difference in inducer size yes, but it makes the same overall and spools the same. We have over 40 pulls on the T04Z car vs the 190 or so on the 11:1 car and I can tell you from firsthand experience that VIII to VIII with S2s they are pretty much identical at 36 psi.
